WARP-THREAD HOLDER FOR LOOMS- SPECIFICATION forming part of LettersPatent No. 779,944, dated January 10, 1905.

To all whom it may concern.-

Be it known that I, HAROLD LEE, a subject of the King of Great Britain,residing at Fairfield, Broughton Park, Manchester, in the county ofLancaster, England, have invented acertain new and useful Warp-ThreadHolder for Looms,of which the following description, in which referenceis madeto the accompanying drawings, is a specification.

During the process or operation of weaving when several of thewarp-threads for any reason or from any cause are broken or otherwisefail to be in continuity considerable inconvenience and delay is causedthe weaver to hold them when being repaired in suitable positions untilthey are finally held by being woven into the fabric. Especially is thisinconvenience experienced in connection with looms having what are knownas warp stop-motions, because the continuity of action of the ,loomdepends upon every thread of warp therein being held in a certain stateof tension,

Hence the necessity of means for enabling the repaired threads to betemporarily secured under the conditions required. To provide meanswhereby this object may be attained, and that without the addition ofparts which would be disadvantageous to the freedom of the weaversactions while carrying out his or her duties, is the object of thisinvention. To attain this object use is made of the devices hereinafterdescribed, and as illustrated by the accompanying sheets of drawings,where- 1n- Figure 1 is a longitudinal section, parts being in elevation,showing the outline of the end frame of a loom from the back to thefront of which is stretched the warp in connection with which mythread-holding device is used. Fig. 2 is a view of certain of the frontparts of a loom with my device applied thereto, as seen from above.Figs. 3, 4, and 5 are side, plan, and end views, respectively, showingmy holding device in detail, drawn to an enlarged scale.

As is well known, the warp a in a loom stretches from the rail 1;, whichis fixed at the back part of the end frame 0 to the rail d, fixed on thefront part thereof, and-when any of the threads of said warp a arebroken or cease to be in continuity on being repaired they have to beheld firmly by their loose ends, which extend toward the rail (Z, untilthey are woven into the fabric, as at the point f. The holding of thesethreads at the necessary tension is more particularly imperative whenany relaxation or slackening of them would allow the parts, such as thedetectors 9 g, to operate and bring about the stoppage of the loom, asis the case when such remission of tension is utilized for detectingbroken threads, so that it is desirable to have ready means for securingthese loose ends to retain the threads at the desired tension no matterat what part of the fabric being woven may such threads be situated.

My holding device consists of the bar it, which extends from one side tothe other over the fabric is to be firmly mounted upon the brackets, ps, which are secured to the front rail cl. Upon this bar it are securedthe series of clips 2? by means of the spanningpieces u and the screwsw. The ends of these clips t are free, so that the extending parts ofthe thread a which have been repaired may be passed while being held ina state of tension laterally under said clips, where by the resilienceof these latter they are held against the bar it, the position of thenewly repaired thread when held by one or other of the clips beingsomewhat as shown at 00, while that of a repaired thread partly woveninto the fabric is as shown at g.

It will be observed that by constructing the clips as above described,provided the weaver neglects to remove from them the threads that hadbeen retained by them after such threads have been woven into thefabric, no undesirable results take place, for the reason that by thecontinued weaving operations the threads retained by the clips arewithdrawn therefrom as the woven fabric passes along.

Such being the nature and object of my said invention, what I claimis- 1. In a loom a thread-holding device consisting of a bar extendingfrom side to side of the fabric being woven, brackets for supporting theends of said bar, and holding-clips mounted on said bar and having freeportions under them of the threads to be held, substan- IO arranged toreceive and lay hold of threads tially as herein described.
